C. L. LA JEUNESSE DUST DISPOSAL DEVICE FOR VACUUM CLEANERS Filed Nov. 25, 1955 ATTORNEYS Patented Sept. 5, 1939 UNITED STATES PATENT OFFICE DUST DISPOSAL DEVICE FOR VACUUM CLEANERS 2 Claims.

My invention relates to improvements in dust disposal devices for vacuum cleaners.

The object of my invention is to provide a readily usable container and dust disposal bag so equipped with an adapter as to make it readily attachable to outlets of a vacuum cleaner bag, whereby to facilitate the transfer of dirt and dust from the vacuum cleaner bag to my device.

Another object of my invention is to provide a device of the class described which is universally adaptable to any vacuum cleaner bag.

In the drawing:

Fig. l is a perspective of a form of dust disposal container and showing the various parts of the container and of a vacuum cleaner dust bag and fittings to be used in conjunction therewith.

Fig. 2 is a perspective of the vacuum cleaner dust bag with my special closure member for the upper portion thereof.

Fig. 3 is an enlarged vertical section through the upper portion of the structure shown in Fig. 2`

Like parts are designated by the same reference characters throughout the several views.

Any vacuum cleaner dust bag |08 which is attacha'ole to its vacuum cleaner by means of a bayonet fitting |09 may be provided with a plug H to be inserted in the fitting |09 when the dust bag is removed from the vacuum cleaner. At the other, normally the upper, end I I, of the vacuum cleaner dust bag, the manufacturer usually provides a clamp to hold in dust-tight rela.

tionship the folding upper end However, I provide in place of the usual clamping means a special adapter H2 shaped with one ange ||2| to t perfectly the flange |01 in the cover H33 of the dust disposal container |00 and another flange H22 to t inside the margins of a vacuum cleaner bag. A bead H23 is riveted between the anges. I clamp the upper margins of the vacuum cleaner dust bag to my adapter H2 b-y means of a clamping ring I|3 and the vacuum cleaner dust bag |08 may be removed from the vacuum cleaner by disengaging the bayonet fitting |09, the plug H0 may be placed in the bayonet fitting |09 to effectually close its opening, and the vacuum cleaner dust bag may then be inverted so that my adapter ||2 may be placed in frictional engagement in the flange |01 for a dust disposal operation.

When a vacuum cleaner bag |08 :litted with my adapter H2 is installed upon a vacuum cleaner for a normal cleaning operation, an adapter cover |44 shown most clearly in Fig. 3, is tted over the adapter H2 and is secured thereto by means of thumb screws H which are receivable in L brackets I6. A gasket at provides dusttight closure of the cover ||4 upon the adapter ||2.

I claim:

l.. A vacuum cleaner dust bag provided with an adapter fitted to connect it with a vacuum cleaner whereby dust may be receivable into the bag, and a dust emptying orifice spaced from said adapter provided with a ribbed marginal itting to engage the bag, a clamping ring to secure the ntting upon the bag, said tting being provided with inwardly projecting brackets, and a cover receivable upon the fitting in dust tight relation and provided with thumb screws to engage the brackets whereby upon removal of the cover to provide an opening for dust disposal.

2. A vacuum cleaner dust bag provided with an adapter tted to connect it with a vacuum cleaner whereby dust may be receivable into the bag, and a dust emptying o-rice spaced from said adapter provided with a ribbed marginal iitting to engage the bag, a clamping ring to secure the fitting upon the bag, said fitting being provided with inwardly projecting brackets, a cover receivable upon the tting in dust tight relation and provided with thumbscrews to engage the brackets whereby upon removal of the cover to provide an opening for dust disposal, and means mechanically associated with said cover whereby to hang the bag therefrom.
